TECHNICAL FIELD

The present invention relates to pyridone derivatives. In detail, the present invention relates to pharmaceutical compositions having a binding activity to the cannabinoid type 2 receptor (pharmaceutical compositions containing pyridone derivatives having an antagonistic activity or an agonistic activity to the cannabinoid type 2 receptor).

BACKGROUND ART

Cannabinoid was discovered as the main active substance contained in marijuana in 1960 and found to exhibit an activity in the central nervous system (illusion, euphoria, sensory confusion of time and space) and in the peripheral cell system (immunosuppressive activity, anti-inflammatory activity, analgesic activity).

After that, anandamide and 2-arachidonoylglycerol produced from arachidonic acid-containing phospholipids were discovered as endogenous agonists to the cannabinoid receptor. These endogenous agonists are known to exhibit an activity to the central nervous system and an activity to the peripheral cell system. It is disclosed in Hypertension (1997) 29, 1204-1210 that anandamide exhibits an activity to the cardiovascular system.

A cannabinoid type 1 receptor discovered in 1990 was found to be distributed over the central nervous system such as the brain. Agonists to this receptor were found to suppress the release of neurotransmitters to cause central actions such as analgesic effect or illusion. A cannabinoid type 2 receptor discovered in 1993 was found to be distributed over immune tissues such as the spleen. Agonists to this receptor were found to suppress an activation of immunocyte or inflammatory cells to exhibit an immunosuppressive activity, an anti-inflammatory activity and an analgesic activity (Nature, 1993, 365, 61-65).

Therefore, antagonists or agonists to the cannabinoid type 2 receptor are expected as immunosuppressive agents, anti-inflammatory agents, and analgesic agents (Nature, 1998, 349, 277-281).

In WO99/02499 and WO00/40562, described as a compound having an antagonistic activity or an agonistic activity to the cannabinoid type 2 receptor are quinolone derivatives. These quinolone derivatives are the compounds having a benzene ring substituted with dialkoxy and a nitrogen atom of the quinolone ring substituted with a hydrogen atom or methyl as shown below.

 

On the other hand, disclosed in EP0481802 and J. Med. Chem. 1998, 36, 953-066 are pyridone derivatives having anti-HIV activity.

Furthermore, disclosed in Japanese Patent Publication Kokai 1983-46068 is a quinolone derivative represented by (A) as an intermediate of medicament, and in J. Chem. Soc. Perkin. Trans. I (1984), p1173-1182 discloses a pyridone derivative represented by (B).

Library A

Combinatorial preparation of 1-butyl-2-oxo-5-aryl-1,2-dihydropyridine-3-carboxylic acid amide derivatives (Combi-A)

  a) Preparation of Resin A-02

To a solution of 4-sulfamylbutyryl AM resin (3.9 g) in methylene chloride (80 mL) were added 1-butyl-5-iodo-2-oxo-1,2-dihydropyridine-3-carboxylic acid (A-01) (4.1 g) and N,N-diisopropylethylamine (3.7 mL) at room temperature. After stirring for 10 min, to the reaction mixture was added PyBOP (6.6 g) at room temperature, and the reaction mixture was stirred for additional 18 h. The resin was filtered off, washed with water, THF, methylene chloride, and diethyl ether one by one to give resin (A-02) [5.2 g, 92% determined by iodine elementary analysis].

b) Preparation of Resins (A-03-01 to A-03-24)

Resin A-02 (150 mg) was measured each in 24 flasks, and to each flasks were added DME (2.5 mL), PdCl₂(dppf) (35 mg), arylboronic acid (5 equivalent), and a 2 M aqueous solution of potassium carbonate (0.34 mL). After stirring at 80° C. for 18 h, the resin was filtered off, washed with water, THF, N-methylpyrrolidone, methylene chloride, and diethyl ether one by one to give resins A-03-01 to A-03-24, respectively.

c) Preparation of Resins A-04-01 to A-04-24

To resins A-03-01 to A-03-24 were added N-methylpyrrolidone (2.0 mL), iodoacetonitrile (0.16 mL), and N,N-diisopropylethylamine (0.1 mL) at room temperature. After stirring for 24 h, the resin was filtered off, washed with N-methylpyrrolidone, methylene chloride, and diethyl ether one by one to give resins A-04-01 to A-04-24, respectively.

d) Preparations of 1-butyl-2-oxo-5-aryl-1,2-dihydropyridine-3-carboxamide Derivatives A-05-01 to A-05-96

Test Example

Test-Examples of the above compounds of the present invention are shown as follows.

Test Example 1 Experiments for Human CB2 Receptor Binding Inhibition

The coding region of human CB2 receptor (CB2R) cDNA (Munro etc, Nature, 1993, 365, 61-65) was inserted into the mammalian expression vector, pSVL SV40 Late Promoter Expression Vector (Amersham Pharmacia Biotech Inc.). The prepared vector was transfected into Chinese Hamster Ovary (CHO) cells with LipofectAMINE reagent (Gibco BRL) according to the manufacture's protocol, and the stable CB2R-expressing clones were selected.

The crude membrane fractions were prepared from the CB2R-expressing CHO cells. Receptor binding assay was performed by incubating the membranes with each test compound and [³H]CP55940 (at a final concentration of 0.5 nM: NEN Life Science Products) in the assay buffer (50 mM Tris-HCl, 1 mM EDTA, 3 mM MgCl₂, pH 7.4) containing 0.5% bovine serum albumin (BSA) for 2 h at 25° C. The incubation mixture was filtered through 1% polyethylenimine-treated GF/C glass filter and washed with 50 mM Tris-HCl (pH 7.4) containing 0.1% BSA. The radioactivity was then counted with a liquid scintillation counter. Non-specific binding was determined in the presence of 10 μM WIN55212-2 (a cannabinoid receptor agonist described in the patent U.S. Pat. No. 508,122, Research Biochemicals International), and the specific binding was calculated by subtracting the non-specific binding from the total binding. The IC₅₀ value for each test compound was determined as the concentration at which 50% of the specific binding was inhibited.

For the receptor binding assay of human CB1 receptor (CB1R), the stable CB1R-expressing CHO cells were prepared as described above, and the binding assay was performed using their membrane fractions. As a consequence of these studies, the Ki values of each test compound for both cannabinoid receptors were determined, which were presented in Table. As shown in this table, a series of compounds described in the present invention were found to block the binding of CP55940 (a cannabinoid receptor agonist described in the patent U.S. Pat. No. 4,371,720) to CB2R.

Test Example 2 Inhibition Experiments for CB2 Receptor-Mediated Suppression of cAMP Synthesis

The CHO cells expressing human CB2R were incubated with test compounds for 15 min. After the incubation, forskolin (final concentration of 4 μM, Sigma) was added and the cells were incubated for 20 min at 37° C. The reaction was stopped by the addition of 1N HCl and the amount of cAMP in the cell supernatant was measured using an EIA kit (Amersham Pharmacia Biotech) according to the manufacture's protocol. The cAMP amount increased by forskolin compared to that in the absence of forskolin was defined as 100%, and the IC₅₀ value of each test compound was determined as the concentration at which 50% of the forskolin-stimulated cAMP synthesis was inhibited. As a consequence of these studies, the IC₅₀ value of each test compound was presented in Table. As shown in Table, the compounds described in the present invention were found to possess agonistic activity for CB2 receptor.

The antagonistic activity of each compound was also evaluated in this assay.

On the otherhand, the compound of the present invention can be evaluated for its anti-inflammatory effecting by the following in vivo studies.

Test Example Experiments for Sheep Red Blood Cell (SRBC)-Induced Delayed Type Hypersensitive (DTH) Reaction

Female ddY mice (7 weeks old) were used, mice were sensitized by the intradermal injection of 10⁷ cells of SRBC into the left hind foot pad (40 μL). After 5 days, DTH reaction was induced by the intradermal injection of 10⁸ cells of SRBC in the right hind foot pad (40 μL). The compounds of the present invention having a binding activity to the cannabinoid type 2 receptor were administerd p.o. (10 ml/kg) at 1 h before and 5 h after the induction of DTH reaction. After 24 h of the injection of SRBC, the left and right foot pad volumes were measured by the water displacement method. The foot pad swelling was calculated as the differences in the volumes between the right and left hind foot pad, and used as an index of the DTH reaction.

Data are expressed as the inhibition percentage of each compound. Statistical analysis was performed with Welch's t-test, in which the value of P<0.05 is considered as a significant difference.
